# Golang bindings for the Telegram Bot API
|
|
|
|
[](http://godoc.org/github.com/Syfaro/telegram-bot-api)
|
|
|
|
All methods have been added, and all features should be available.
|
|
If you want a feature that hasn't been added yet or something is broken, open an issue and I'll see what I can do.
|
|
|
|
All methods are fairly self explanatory, and reading the godoc page should explain everything. If something isn't clear, open an issue or submit a pull request.
|
|
|
|
The scope of this project is just to provide a wrapper around the API without any additional features. There are other projects for creating something with plugins and command handlers without having to design all that yourself.
|
|
|
|
## Example
|
|
|
|
This is a very simple bot that just displays any gotten updates, then replies it to that chat.
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"log"
|
|
"github.com/Syfaro/telegram-bot-api"
|
|
)
|
|
|
|
func main() {
|
|
bot, err := tgbotapi.NewBotAPI("MyAwesomeBotToken")
|
|
if err != nil {
|
|
log.Panic(err)
|
|
}
|
|
|
|
bot.Debug = true
|
|
|
|
log.Printf("Authorized on account %s", bot.Self.UserName)
|
|
|
|
u := tgbotapi.NewUpdate(0)
|
|
u.Timeout = 60
|
|
|
|
err = bot.UpdatesChan(u)
|
|
if err != nil {
|
|
log.Panic(err)
|
|
}
|
|
|
|
for update := range bot.Updates {
|
|
log.Printf("[%s] %s", update.Message.From.UserName, update.Message.Text)
|
|
|
|
msg := tgbotapi.NewMessage(update.Message.Chat.ID, update.Message.Text)
|
|
msg.ReplyToMessageID = update.Message.MessageID
|
|
|
|
bot.SendMessage(msg)
|
|
}
|
|
}
|
|
```
|
|
|
|
If you need to use webhooks for some reason (such as running on Google App Engine), you may use a slightly different method.
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"github.com/Syfaro/telegram-bot-api"
|
|
"log"
|
|
"net/http"
|
|
)
|
|
|
|
func main() {
|
|
bot, err := tgbotapi.NewBotAPI("MyAwesomeBotToken")
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
|
|
bot.Debug = true
|
|
|
|
log.Printf("Authorized on account %s", bot.Self.UserName)
|
|
|
|
_, err := bot.SetWebhook(tgbotapi.NewWebhookWithCert("https://www.google.com:8443/"+bot.Token, "cert.pem"))
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
|
|
bot.ListenForWebhook()
|
|
go http.ListenAndServeTLS("0.0.0.0:8443", "cert.pem", "key.pem", nil)
|
|
|
|
for update := range bot.Updates {
|
|
log.Printf("%+v\n", update)
|
|
}
|
|
}
|
|
```
|
|
|
|
If you need, you may generate a self signed certficate, as this requires HTTPS / TLS. The above example tells Telegram that this is your certificate and that it should be trusted, even though it is not properly signed.
|
|
|
|
openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 3560 -subj -nodes
